Reproducing the integer count of black hole micro-states from the gravitational path integral
is an important problem in quantum gravity. In this paper, we show that, by using …

We invoke the black-hole–qubit correspondence to derive the classification of four-qubit
entanglement. The U-duality orbits resulting from timelike reduction of string theory from D …

We give a review of the black-hole/qubit correspondence that incorporates not only the
earlier results on black-hole entropy and entanglement measures, seven qubits and the …

We detail the construction of the most general asymptotically flat, stationary, rotating,
nonextremal, dyonic black hole of the four-dimensional N= 2 supergravity coupled to 3 …

We build a number of integrable one-scalar spatially flat cosmologies, which play a natural
role in inflationary scenarios, examine their behavior in several cases and draw from them …

We derive the explicit action of the U-duality group of the STU model on both BPS and non-
BPS extremal multi-center solutions. As the class of known non-BPS extremal solutions is …

We describe the most general asymptotically flat, stationary, non-extremal, dyonic black hole
of the four-dimensional N= 2 supergravity coupled to 3 vector multiplets that describes the …

We explain how to exploit systematically the structure of nilpotent orbits to obtain a solvable
system of equations describing extremal solutions of (super-) gravity theories, ie systems …

A bstract Using algebraic tools inspired by the study of nilpotent orbits in simple Lie
algebras, we obtain a large class of solutions describing interacting non-BPS black holes …

We complete the classification of half-supersymmetric branes in toroidally compactified
IIA/IIB string theory in terms of representations of the T-duality group. As a by-product we …
